SPECIFCATIGN forming part of Letters Patent No. 645,006, dated March 6,1900. Application-filed August 3, `1899. Serial No. 726,048. (Nitmodel.)

To @U whom it may concern: Be it known that I, JOHN M. PFAUDLER, oRochester, in the county of Monroe and State of New York, have inventedcertain new and usefullmprovements in Lamps; and I do hereby declare thefollowing tobe a full, clear, and enact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the o reference-numerals marked thereon.

My present invention relates to improve-V ments in lamps, particularlythat class em- -ploying round wicks, though some of the featuresareapplicable to other forms, and has for its` objects to' improve theconstruction and operation of the various parts, all as will behereinafter described, and the novel features pointed outin the claimsat the end of this specitication.

In the drawings, Figure 1 is a sectional view of a lamp fount and burnerconstructed in accordance with myinvention. Fig. 2isa side elevation ofthe burner. Fig. 3 is a similar view showing the chimney gallery orsupport in the elevated position. Fig. 4 is a sectional view on the line4 4 of Fig. l; and Fig. 5 is a View, partly in section, showing theconstruction of the wick-raiser. Fig. 6 is a per,- spective View of theextin guisher-rin g and its operating-lever.

Similar reference-nu 1n erals indicate similar parts.

The lamp-body consists of Vthe oil font or reservoir,having the hollowcylindrical drafttube 2 arranged centrally therein, and, eX- tendingupwardly, supports the perforated spreader 3 and is surroundedby theburner, supported on the top portion 4 of the fount.

The burner embodiesthe circular ring or base 5, secured to the internaltube or sleeve 6, adapted to surround the wick, and extend upward to theupper extremity of the drafttube 2 and having the rim '7 threaded uponits outer edge and adapted to be secured into the top 4 of the fount.

8 indicates a ring secured upon the interior of the rim 7, havingmounted upon it the i shell or casing 9, forming they exterior of theburner. The chimney-gallery rests upon the top of the casing 9 and inthe present construction embodies the ring 10,the springfingers 11, theglobe or shade support 12, the skeleton plate 14, connected thereto, andthe perforated cone-shaped plate 13. Extending downwardly from the ring10 is a collar or skeleton plate 14, fitting the interior of theburner-shell 9 and provided with the spiral car-tracks 15 and theVertical Ways or guides 16. Revolubly mounted upon the flange 1S of theshell 9 is a collar 17 having screws or from their lower sides andarranged parallel i to the ways 16, which facilitate the removal of thismechanism from the burner-body when desired. As the ring or collar 17 isrevolved the pins 19 operate against the sides of the ways 16, revolvingthe skeleton frame 14 upon the burner, causing the inclined or spiralways 15 to be moved against the stationary pins or studs 21 and to bethus elevated. By this construction the operator is only required torotate theV collar 17, and the necessity of following thechimney-gallery in its ascent with the hand is entirely obviated.

The upper end of the draft-tube 2 is provided with a series ofperforations adapted to register 'with apertures 23 in the distributer 3to allow air to pass into the upper end of the wick to facilitatecombustion. The

spreader 3 is fitted loosely into the upper end of the draft-tube 2 andsecured in position by means of pins or lugs 24, projecting inwardly andadapted to be engaged beneath the annular rim 25, cut away at 2G uponopposite "sides, as shown in dotted lines, Fig. 1, and mounted upon thering 27', secured upon 6o pins 19 operating through horizontal slots 20r vof the extinguisher sleeve or tube 30.

the interior of the draft-tube. 28 indicates a series of apertures topermit the escape of any oil that may have worked over the top of thetube 2 or through the apertures 23 while the wick has not been lighted,and for the lsame purpose I provide apertures 29 in the burner-base 5.

'The upper end of the distributer 3 ilares outwardly over the annularwick-recess between the draft-tube and the inner portion 6 of theburner. The extinguisher is constructed of a sleeve or tube 30, capableof vertical movement on theV tube G, its top nor-v mally resting in linewith the top thereof, and supported upon the lower end by an annularflange 3l, secured to the burner by arms 32. The vertical movement ofthe extinguisher is accomplished by means of a lever 33, pivoted at 3 4to the burner-shell 9, having the bifurcated ends slotted at 35 andengaging pins 3G, vlocated upon the opposite sides The latter is guidedin its movement by the tube G and held in its elevated position inengagement with the overhanging edge of the defiector by frictionalengagement between the parts, a portion of the lower part of theextinguisher sleeve or tube being cut away, leaving the ribs 37, whichmay be bent inwardly before the tube is positioned to create the desiredfriction between the parts.

As before mentioned, the deiiector 3 is loosely mounted upon the upperend of the draft-tube and prevented from excessivevertical movement bymeans of the pins 24,which are normally slightly below the rim 25 of thering 27. By this arrangement the deflector is allowed to yield whenengaged by the eX- tinguisher and t0 completely close the top of thelatter, preventing the escape of smoke or other obnoxious gases when theflame is extinguished.

The lamp-wick 40 is of course adapted to be raised or lowered to givethe desired height of iiame, and for this purpose I provide awick-raising device arranged within the fou nt and consisting of avertically-movable ring 4l, surrounding the wick and carrying twooppositely-arranged wings or engaging members 42, hinged thereto at 43and adapted to extend upward,surrounding and engaging the wick at apoint within the burner-tube 6. The wings are formed from thin sheetmetal and are adapted to lie against the wick and to be held inengagement therewith by the burner-tube 6, and to insure the evenmovement of the wick the upper edges of the wings are provided withinwardly-projecting teeth or prongs, (not shown,) and other projectionsupon the sides of the wings bent inwardly from the V-shaped apertures 44ene gage the wick securely. The hinged connection between the ring '4land the wings permits the latter to be separated, as shown 'in dottedlines, when the burner has been removed, allowing the wick to bewithdrawn and a new one substituted when desired. Arranged upon one sideof the ring 4l is anarm 45, provided upon its extremity with a nut 46,engaging a revoluble post 47, journaled upon its lower end in a bearing48 and having the quick thread 49. The upper extremity of the postprojects through the screw-cap 50,

54, located at the side of the fount, which arrangement centers andguides the wick-raising mechanism and also prevents the nut 46 frombeing moved out of alinement with the aperture 5l either in removing'orinserting the post. l.

In order that the amount ot' o-il contained in the lamp can be readilyascertained at any time or during the filling operation, I provide anautomatic indicating device arranged within the fount and visiblethrough a window or aperture 60, provided with a transparent covering.Pivotally mounted upon a sup-` port 6l is an upwardly-extending arm G2,carrying a curved indicating-plate 65, provided with suitable markingsto indicate the level ofthe oil. Rigidly attached at an angle to thesaid arm is an extension 64, provided at its extremity with a iloat,adapted to rest upon the surface of the oil, and as the heightl of thelatteris changed to move the indicator 63 correspondingly.

The improvements described are capable of being fitted to lamps alreadyin use. The extinguishing device can be applied to any IOO lamp ot' theclass described having an external wick-*tube and the spreader providedwith the broad top with which to cooperate.
